Abstract

The invention provides an ethylene-acrylic ester rubber product and a preparation method thereof. The ethylene-acrylic ester rubber product is prepared from the following components in parts by weight: 100 parts of ethylene-acrylic ester, 100 to 120 parts of medium particle thermal cracking carbon black, 10 to 15 parts of a plasticizer, 1 to 1.5 parts of stearic acid, 1.5 to 2 parts of a vulcanizing agent and 4 to 5 parts of a promoter, wherein the ethylene-acrylic ester consists of high-Mooney ethylene-acrylic ester and low-expansion ethylene-acrylic ester according to the mass ratio of (70 to 80):(20 to 30). The preparation method of the ethylene-acrylic ester rubber product comprises the following steps: mixing all the raw material components according to the formula amounts to obtain mixed rubber, and then carrying out open forming, primary vulcanization and secondary vulcanization to obtain the ethylene-acrylic ester rubber product. The ethylene-acrylic ester rubber product provided by the invention is relatively high in strength, relatively wide in use temperature range and relatively high in high temperature resistance, compression deformation resistance and engine oil resistance.

Description

technical field

[0001] The invention belongs to the technical field of composite rubber materials, and in particular relates to an ethylene acrylate rubber product and a preparation method thereof. Background technique

[0002] Car engines need to use engine oil to lubricate their moving parts. In order to prevent oil leakage, rubber rings are generally used to seal the parts. Engines that use fuel have a higher service temperature and higher temperature resistance requirements for rubber rings. Generally, acrylate or fluororubber with higher temperature resistance is selected as the sealing material. Acrylate has a very large cost advantage, so it is more widely used in the sealing of engine oil. Ethylene acrylate has better high temperature resistance and processing performance than ordinary acrylate, and can replace ordinary acrylate rubber.

[0003] The combustion temperature of the fuel in the turbocharged engine is much higher than that of the naturally aspirated eng...
